Channel and Track

Channel and Track Panel

• You can click the Track Panel on the left to view and manage all channels and tracks.
• A Channel contains a predefined set of tracks grouped by data type.

Expand Channel

A channel may contain multiple individual tracks. To expand a channel and view all its tracks:

1. Split Track in Channel
   Each track in a channel contains multiple attributes. You can split or organize signals based on your needs. For example, you can generate a track list by RNA-binding protein or cell line. The number shown on the far left of each track indicates the total number of features in that track. The track label displays the corresponding attributes.

2. Search Track in Channel
   You can search for specific tracks within a channel by keyword. This feature will allow you to quickly locate tracks of interest.

Load Track

1. Open the Track Panel
   Click the Track button in the left sidebar to open the track operations panel. You can choose different track loading methods depending on your needs.

2. Choose Local Files
   Use the file loader to import data from your local computer.

   

   Warning

   To protect user privacy, local files are not uploaded to the RBrowser backend. Instead, they are parsed and rendered directly in the local browser environment. Loading and visualization speed mainly depends on file size, local disk speed, browser performance, and, for remote files, network bandwidth. Modern browsers, such as Chrome, do not allow persistent access to locally loaded files after a session is saved. Therefore, if you need to preserve and reopen a session, we recommend loading tracks from Remote or DataHub instead of local files.

3. Drag Local Files
   Drag and drop files directly into the RBrowser Main Viewer — they’ll be automatically parsed and rendered.

   

   Tips

   The quickest way to load local files is to drag and drop them directly onto the RBrowser window.

4. Load Remote Files
   First, select Remote from the dropdown. Then click Add Remote Track to open the remote track loader.First, select Remote from the dropdown. Then click Add Remote Track to open the remote track loader.

   

   Tips

   RBrowser can automatically detect bioinformatics files, including the file format and accessibility. If the data requires an index (e.g., bed.gz), you need to provide both the data file and its index file.

5. Load DataHub Data Source
   You can open the DataHub to browse and load RNA-centric curated datasets.
